Systems, methods, and machine-storage medium for classifying snapshot image processing are described. The system receives read requests to read snapshot information. Each read request includes an offset identifying a storage location and a length. The snapshot information includes snapshots including a full snapshot and at least one incremental snapshot. The read requests include a first read request to read data from the snapshot information. The system generates a first plurality of read events including a second plurality of read events that are generated by processing the first read request. The second plurality of read events includes first and a second read events. The system identifies whether utilizing a cache optimizes the job based on the first plurality of read events.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The system of claim 2, wherein the plurality of snapshots includes snapshots that respectively correspond to snapshot levels and snapshot level identifiers.
4. The system of claim 2, wherein the at least one count of aggregated duplicate read events for the plurality of snapshots includes a count of aggregated duplicate read events for a base snapshot.
5. The system of claim 2, wherein the at least one count of aggregated duplicate read events for the plurality of snapshots includes a count of aggregated duplicate read events for an incremental snapshot.
9. The system of claim 2, wherein the first read request includes a first offset and a first length and wherein the first read event includes the first offset and a second length and wherein the second read event includes a third offset and a third length.
12. The method of claim 11, wherein the plurality of snapshots includes snapshots that respectively correspond to snapshot levels and snapshot level identifiers.
13. The method of claim 11, wherein the at least one count of aggregated duplicate read events for the plurality of snapshots includes a count of aggregated duplicate read events for a base snapshot.
14. The method of claim 11, wherein the at least one count of aggregated duplicate read events for the plurality of snapshots includes a count of aggregated duplicate read events for an incremental snapshot.
15. The method of claim 11, wherein identifying whether utilizing a cache optimizes the job based on the first plurality of read events includes comparing a percentage of duplicate reads with a predetermined threshold.
16. The method of claim 15, wherein comparing the percentage of duplicate reads with the predetermined threshold includes utilizing a bloom filter.
17. The method of claim 11, wherein identifying whether utilizing a cache optimizes the job based on the first plurality of read events includes comparing a percentage of early reads with a predetermined threshold.
18. The method of claim 11, wherein the first read request includes a first offset and a first length and wherein the first read event includes the first offset and a second length and wherein the second read event includes a third offset and a third length.
